Differentiated-type vulvar intraepithelial neoplasia (dVIN) is a non-human papilloma virus (HPV)-related precursor lesion to vulvar squamous carcinoma. The terminology has only become recognized clinically and histopathologically in recent years despite being described more than 50 years ago. As opposed to the HPV-related VIN (uVIN), dVIN has different features of histomorphology, risk of progression, and molecular pathogenesis. Read More

Several antiepileptic drugs (AEDs) are approved by the US Food and Drug Administration for the treatment of bipolar disorder (valproic acid, divalproex, lamotrigine, carbamazepine) and some cutaneous neuropathic pain syndromes (carbamazepine, gabapentin, pregabalin). The AEDs may be effective in the management of (1) chronic pruritus, including pruritus due systemic disease, including uremia, neuropathic pain, neuropathic pruritus, and complex cutaneous sensory syndromes, especially where central nervous system (CNS) sensitization plays a role; (2) management of emotional dysregulation and the resultant repetitive self-excoriation or other cutaneous self-injury in patients who repetitively stimulate or manipulate their integument to regulate emotions (prurigo nodularis, lichen simplex chronicus, skin picking disorder, trichotillomania); (3) management of dermatologic clinical manifestations associated with autonomic nervous system activation (hyperhidrosis, urticaria, flushing; these often occur in conjunction with psychiatric disorders with prominent autonomic activation and dysregulation, eg, social anxiety disorder, posttraumatic stress disorder); and (4) when certain anticonvulsants have a direct therapeutic effect (eg, in psoriasis); currently the use of AEDs for such cases is largely experimental. Gabapentin (dosage range 300-3600 mg daily) is the most widely studied AED mood stabilizer in dermatology and is especially effective in situations where CNS sensitization is a mediating factor.

Diagnosis of genital inflammatory disorders may be difficult for several reasons, such as their similar appearance, possible misdiagnosis with infectious and malignant conditions, and peculiar anatomic conditions that may lead to modification of clinical features. Dermoscopy could be included as a part of the clinical inspection of genital diseases to support diagnosis, as well as to ideally avoid unnecessary invasive investigation. Practical guidance for the use of dermoscopy in the assessment of the main inflammatory genital diseases is provided, namely for lichen sclerosus, lichen planus, psoriasis, lichen simplex chronicus, and plasma cell mucositis.

High-grade vulvar intraepithelial neoplasia, a precursor lesion to vulvar squamous cell carcinoma, is subdivided into 2 types, classic or usual vulvar intraepithelial neoplasia (CVIN) and differentiated vulvar intraepithelial neoplasia (DVIN). CVIN, which is a human papilloma virus (HPV)-dependent lesion, is typically distinguished from DVIN, a p53 mutation-dependent process, by its distinct histomorphologic and immunohistochemical characteristics. However, distinguishing between the 2 entities becomes challenging in cases of CVIN with superimposed inflammatory changes, especially lichen simplex chronicus (LSC). Read More

In severe cases of atopic dermatitis (AD) systemic treatment is indicated. So far, cyclosporine and systemic glucocorticosteroids represented the only systemic treatment options approved for the indications of AD in Germany; however, from clinical practice there is increasing evidence for beneficial therapeutic effects in AD by other immunosuppressive or immunomodulatory substances, such as mycophenolate, methotrexate, alitretinoin and ustekinumab. Beyond this, ongoing research activities focus on a better understanding of genetic and immunological aspects of this chronic inflammatory skin disease. Read More

Dissociation and conversion (defined as the somatic component of dissociation) can play an important mediating role in the exacerbation of the stress-reactive dermatoses (eg, psoriasis, idiopathic urticaria, atopic dermatitis), dermatoses that are exacerbated by excessive scratching (eg, lichen simplex chronicus, prurigo nodularis) and koebnerization, and the self-induced dermatoses (dermatitis artefacta, acne excoriée, skin picking disorder, trichotillomania, onychotillomania/onychophagia). Dissociative symptoms often coexist with obsessive-compulsive symptoms in the more severe cases of the self-induced dermatoses. Dissociation can play an important role in cutaneous sensory disorder (eg, scalp dysesthesia syndrome, stomatodynia/glossodynia, vulvodynia/scrotodynia, medically unexplained anesthesia). Read More

Individuals with obsessive-compulsive features frequently visit dermatologists for complaints of the skin, hair or nails, and often progress towards a chronic relapsing course due to the challenge associated with accurate diagnosis and management of their psychiatric symptoms. The current DSM-5 formally recognizes body dysmorphic disorder, trichotillomania, neurotic excoriation and body focused repetitive behavior disorder as psychodermatological disorders belonging to the category of Obsessive-Compulsive and Related Disorders. However there is evidence that other relevant skin diseases such as delusions of parasitosis, dermatitis artefacta, contamination dermatitis, AIDS phobia, trichotemnomania and even lichen simplex chronicus possess prominent obsessive-compulsive characteristics that do not necessarily fit the full diagnostic criteria of the DSM-5.

Differentiated vulvar intraepithelial neoplasia (dVIN), precursor of vulvar squamous cell carcinoma, is human papilloma virus independent and often found in a background of lichen sclerosus (LS) and lichen simplex chronicus (LSC). Subtle histologic findings make the diagnosis of dVIN difficult, and, although the use of p53 and Ki-67 has been of some value, there is a need for a better immunohistochemical marker. Cytokeratin 17 (CK17), a cytoskeletal intermediate filament protein, has previously been used in the diagnosis of anogenital lesions. Read More
